Cortex Matures Faster in Youth with Highest IQ (IMAGE)
Caption
The developmental trajectory of waxing and waning in cortex thickness differs as the brain matures in different IQ groups. Thickness of the area at the top/front/center, highlighted in MRI brain maps at left, peaks relatively late, at age 12 (blue arrow), in youth with superior intelligence, perhaps reflecting an extended critical period for development of high-level cognitive circuits.
